Wiring accessories to the EMS
Please follow this suggested wiring diagram when adding new accessories and
retaining original accessories such as the multiplex coolant temperature gauge, air
conditioning switch, reverse lockout, UEGO gauges, MAP sensors, IAT sensors, or
switches for use with the EMS. Note that wire polarity is not important for the Air
Temperature sensor.

30-1030 (Series 1) vs 30-6030 (Series 2) EMS differences:
The EMS functions assigned to certain pins have been changed and no longer match the 30-
1030 EMS. Unless otherwise noted, the following pins and functions will need to be manually
reconfigured after using AEMTuner to convert a V1.19 30-1030, Series 1 EMS calibration for
use with the 30-6030 Series 2 hardware.
